BPE's mission is to drive exceptional outcomes for all students by developing great teachers and great schools. Since its establishment in 1984 by corporate and philanthropic leaders to reform Boston's schools, BPE has focused on fulfilling a basic promise of democracy: that every child should have access to a free, quality public education. For thirty years, BPE has devised solutions to the toughest challenges faced by Boston's students and teachers by weaving together expertise in teacher and school development. BPE has demonstrated its capacity to institute, study and scale up reforms by sharing their work and making tools publicly available. They have incubated successful practices, such as Collaborative Coaching and Learning, cutting edge data tools using early warning indicators and Boston Teacher Residency that have spread across both Boston and the nation more broadly.
